NOTE :
The manual selector is driven by the fuel unit and is positioned on R or L mark
corresponding to the tank selected by the sequencer. Therefore, the pilot
continuously knows the tank which is operating.
Test for system proper operation
”SHIFT” push--knob allows the pilot to test system proper operation anytime.
When the system operates, the fuel tank is changed when ”SHIFT”
push--knob is pressed once.
If airplane is on ground or in flight, low level CAS messages not visible, the
new selected tank remains operating and a new sequence is initiated.
NOTE :
This procedure allows the pilot to preferably choose the tank from which he
wants to take fuel.
In all cases, proper system operation is indicated by rotation of the manual
selector.
Setting ”FUEL SEL” switch to MAN position or setting manual selector to OFF
position leads to system de--activating and appearance of ”AUTO SEL” CAS
message. ”AUTO SEL” CAS message also lights on when order given by the
sequencer has not been executed after 12 seconds.
ELECTRIC BOOST PUMP (”AUX BP”)
Electric boost pump is an auxiliary pump located between fuel unit and main
mechanical boost pump. It is controlled through ”AUX BP” switch located on
”FUEL” panel. This switch allows stopping or selecting the two pump
operating modes :
-- when set to ON, electric boost pump operates permanently
-- when set to AUTO, electric boost pump is automatically operated in case
of fuel pressure drop at the mechanical boost pump outlet.
